You didn't mention this in the description, but yeah - Using select
probably makes more sense here.

This should go before the iiod comments to ensure it gets indented under
the iiod option in menuconfig.

I did a quick test build and I see it fails to link with older
toolchains as usbd.c doesn't get built.

Looking at the kernel history the usb_functionfs_descs_head_v2 structure
seems to have been added in 1df22b4ea9d91, so I added a
BR2_TOOLCHAIN_HEADERS_AT_LEAST_3_18 dependency and updated the comment
below.

Committed with that fixed, thanks.
